Aren't comp tickets great? I got to see Bonnie Raitt at Red Rocks in Colorado with tickets from JVC. Bruce Hornsby opened for her, and she brought her father John out to do a couple of songs with her.
I saw the Voodoo Lounge tour at Soldier Field in Chicago. We didn't have tickets so we went to the ticket office at the gate and didn't have any choice in the tickets that we bought.
